我正在尝试使用 Rime 和 REST 创建一个充当网关的 ContikiOS 固件。网关必须通过 Rime 网格与其他微尘通信，并且可以通过 REST API 与外部通信。

以下代码是两个默认 Contiki 示例（rest-example/rest-server-example.c 和 rime/example-mesh.c）的组合。因此我包括“rest.h”、“net/rime.h”、“net/rime/mesh.h”。

问题是当我尝试使用以下 makefile 编译此固件时，rime 文件不会包含在 obj_sky 中，并且我在固件中使用的任何 Rime 函数都会出现“未定义引用”错误。但是，当我删除 makefile 中的行和固件代码中引用 REST 的任何代码时，它会编译（并将 rime 文件添加到 obj_sky）。

有没有人知道为什么在添加 rest-http 应用程序后没有添加 rime 以及我可以做些什么来编译它？

谢谢
